On April 7,2013 while tent camping in the park at about 4:30am or so, I heard what sounded like a woman screaming at the top of her lungs! As this sound got closer, I could tell it was not a human. This sound was in the park and very close to my tent, about 100yds.away or so. I resaerched the sound I heard and I am sure that it was a Moutain Lion scream! The IDNR should revisit the opinion regarding Mountain Lions in the Shawnee! Still, I enjoyed the cave, hiking and camping in the park in general.
